About This Manual
• The operational procedures for Modules 2858, 2859, 2860, and 2861 are identical.
All of the illustrations in this manual show Module 2858/2859.
• Button operations are indicated using the letters shown in the illustration.
• Each section of this manual provides you with the information you need to perform
operations in each mode. Further details and technical information can be found in
the “Reference” section.
If the display of the watch is blank...
If the sleep indicator (SLEEP ) is displayed, it means the
watch’s Power Saving function has turned off the display
to conserve power. Power Saving automatically turns off
the display and enters a sleep state whenever the watch
is left for a certain period where it is dark.
• The initial factory default setting is Power Saving on.
• The watch recovers from the sleep state if you move it to
a well-lit area* , if you press any button, or if you angle
the watch towards your face for reading.

Last Signal Screen
• This watch is designed to pick up the time calibration signal transmitted from Rugby,
England and the signal from Mainflingen, Germany.
Current Time Setting
This watch automatically adjusts its time setting in accordance with a time calibration
signal. You can also perform a manual procedure to set the time and date, when
necessary.
• The first thing you should do after purchasing this watch is to set your Home City,
which is the city where you will normally use the watch. For more information, see
“To set your Home City” below.
• When using the watch that is outside of the range of the transmitters in Rugby and
Mainflingen, you need to manually adjust the time as required. See “Timekeeping”
for information about manual settings.
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
• Auto Receive
With auto receive, the watch automatically picks up the time calibration signal five
times a day at 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. For more
information, see “About Auto Receive”.
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive”.
Important!
• Position the watch as shown in the nearby illustration, with its 12 o’clock side facing
towards a window. Make sure there are no metal objects nearby.

Operation Guide 2858 2859 2860 2861
• Signal reception is normally better at night than during the day.
• Time calibration signal reception takes from two to five minutes, but in some cases it
can take as long as 12 minutes. Take care that you do not perform any button
operations or move the watch during this time.
1,500 kilometers
Rugby
500 kilometers
Mainflingen
• This watch is designed to receive the time calibration signal transmitted from Rugby,
England and the signal from Mainflingen, Germany. Signal reception is possible
within the area represented by a circle with a radius of about 1,500 kilometers.
• At distances further than about 500 kilometers from a transmitter, signal reception
may not be possible during certain times of year or times of day. Radio interference
may also cause problems with reception.
• See the information under “Signal Receive Troubleshooting” if you experience
problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches 0:00 a.m., 1:00
a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will
also perform an additional auto receive operation at 5:00 a.m. if none of the regularly
scheduled auto receive operations are successful.
Note
• Auto receive is on whenever the transmitter mode setting is anything other than
OFF. See “Transmitters” for more information.
• The auto receive operation is performed only if the watch is in the Timekeeping
Mode or World Time Mode when one of the calibration times is reached. It is not
performed if a calibration time is reached while an alarm is sounding, or while you
are configuring settings (while settings are flashing on the display).
• Auto receipt of the calibration signal is designed to be performed early in the
morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
Before going to bed for the night, remove the watch from your wrist, and put it in a
location where it can easily receive the signal.
• When auto receive is turned on, the watch receives the calibration signal for two to
five minutes everyday when the time in the Timekeeping Mode reaches each of the
calibration times. Do not perform any button operation within five minutes before or
after any one of the calibration times. Doing so can interfere with correct calibration.
• Remember that reception of the calibration signal depends on the time kept in the
digital display. The receive operation will be performed whenever the display shows
any one of the calibration times, regardless of whether or not the displayed time is
actually the correct time.
• When two, three, four, or five receptions are successful, the watch uses the data of
the last reception for calibration. When only one reception is successful, the watch
uses the data of the successful reception.
About the Receiving Indicator
The receiving indicator shows the strength of the calibration signal being received. For best
reception, be sure to keep the watch in a location where signal strength is strongest.
Module 2858/2859
Module 2860/2861
Receiving indicator
(Level 1) Weak
Strong (Level 4)
• Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receiving indicator to indicate signal strength.
• Use the receiving indicator as a guide for checking signal strength and for finding the
best location for the watch during signal receive operations.
• The Level 4 receiving indicator remains on the display in all modes following
reception of the time calibration signal and calibration of the watch’s time setting.
The Level 4 receiving indicator is not displayed if signal reception was unsuccessful
or after manual adjustment of the current time setting.
• The Level 4 receiving indicator is displayed only when the watch is able to
successfully receive both time and date data. It does not appear when only time data
is received.
• The Level 4 receiving indicator indicates that at least one of the calibration signal
receive operations was successful. Note, however, that the Level 4 receiving
indicator is cleared from the display at 3:00 a.m. each day.
To perform manual receive
1. Place the watch on a stable surface so its top (12
o’clock side) is facing towards a window.
• Note that signal reception is poor when the 12 o’clock
side of the watch is not facing towards a window.
2. In the Timekeeping Mode (Current Time screen), hold
down D for about two seconds until the watch beeps.
3. Release D and the message RC! appears to indicate
that signal reception has started.
• Time calibration signal reception takes from two to five
Receiving indicator
minutes. Take care that you do not perform any button
operations or move the watch during this time.
• After signal reception is complete, the display of the watch changes to the Last
Signal screen.
Note
• To interrupt a receive operation and return to the Timekeeping Mode, press D.
• If the receive operation is unsuccessful, the message ERR appears on the display
for about one or two minutes. After that, the watch returns to the Timekeeping Mode.
• You can also change from the Last Signal or ERR screen to the normal
timekeeping screen by pressing D.

Operation Guide 2858 2859 2860 2861
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signals transmitted from Rugby and Mainflingen include both
Standard Time and DST data. When the Auto DST setting is turned on, the watch
switches between Standard Time and DST (summer time) automatically in
accordance with the received time signal.
• The default DST setting is Auto DST (AUtO) whenever you select LON, PAR,
BER, or ATH as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it is
probably best to switch between Standard Time and Daylight Saving Time (summer
time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down A until the city code setting starts to flash,
which indicates the setting screen.
2. Press C twice and the DST setting screen appears.
3. Use D to cycle through the DST settings in the sequence shown below.
Important!
• Storing the watch for long periods in an area where there is no light or wearing it in
such a way that it is blocked from exposure to light can cause rechargeable battery
power to run down. Be sure that the watch is normally exposed to bright light
whenever possible.
• This watch employs a solar cell that converts light into electricity, which charges a
built-in rechargeable battery. Normally, the rechargeable battery should not need
replacement, but after very long use over a number of years, the rechargeable
battery may lose its ability to achieve a full charge. If you experience problems
getting the rechargeable battery to a full charge, contact your dealer or CASIO
distributor about having the rechargeable battery replaced.
• The rechargeable battery should be replaced with a CASIO-specified CTL1616
battery only. Other rechargeable batteries can cause damage to the watch.
• All data stored in memory is deleted, and the current time and all other settings
return to their initial factory defaults whenever battery power drops to Level 4 and
when you have the battery replaced.
• Turn on the watch’s Power Saving function and keep it in an area normally exposed
to bright light when storing it for long periods. This helps to keep the rechargeable
battery from going dead.

About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on for about one second,
whenever you position your wrist as described below in any mode. Note that this
watch features a “Full Auto EL Light,” so the auto light switch operates only when
available light is below a certain level. It does not turn on the backlight under bright
light.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you more than 40 degrees causes the backlight to turn on.

Warning!
• Always make sure you are in a safe place whenever you are reading the
display of the watch using the auto light switch. Be especially careful when
running or engaged in any other activity that can result in accident or injury.
Also take care that sudden illumination by the auto light switch does not
surprise or distract others around you.
• When you are wearing the watch, make sure that its auto light switch is turned
off before riding on a bicycle or operating a motorcycle or any other motor
vehicle. Sudden and unintended operation of the auto light switch can create a
distraction, which can result in a traffic accident and serious personal injury.

• The flashing CHARGE indicator at Level 3 tells you that battery power is very low,
and that exposure to bright light for charging is required as soon as possible.
• At Level 4, all functions are disabled and settings return to their initial factory
defaults. Functions are enabled once again after the rechargeable battery is
charged, but you need to set the time and date after the battery reaches Level 3
from Level 4. You will not be able to configure any of the other settings until the
battery reaches Level 2 after dropping to Level 4.
• Display indicators reappear as soon as the battery is charged from Level 4 to Level 3.
• Leaving the watch in direct sunlight or some other very strong light source can
cause the battery power indicator to temporarily show a reading that is higher than
the actual battery level. The correct battery power indicator should appear after a
few minutes.
• If you use the backlight or the alarms a number of times during a short period, the
recover indicator (RECOVER ) appears on the display and the following operations
become disabled until battery power recovers.

Calibration reception
After some time, battery power will recover and the recover indicator (RECOVER )
will disappear, indicating that the above functions are enabled again.
• If the recover indicator appears frequently, it probably means that remaining battery
power is low. Leave the watch in bright light to allow it to charge.
Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving
the watch in the areas described below whenever charging its rechargeable battery.
Also note that allowing the watch to become very hot can cause its liquid crystal
display to black out. The appearance of the LCD should become normal again when
the watch returns to a lower temperature.
To turn the auto light switch on and off
In any mode, hold down L for about two seconds to toggle the auto light switch on
(auto light switch on indicator displayed) or off (auto light switch on indicator not
displayed).
• The auto light switch on indicator is on the display in all modes while the auto light
switch is turned on.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can cause it
to become quite hot. Take care when handling the watch to avoid burn injury.
The watch can become particularly hot when exposed to the following
conditions for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight

This watch is equipped with a solar cell and a rechargeable battery (secondary
battery) that is charged by the electrical power produced by the solar cell. The
illustration shown below shows how you should position the watch for charging.
Example: Orient the watch so its face
is pointing at a light source.
• The illustration shows how to position
a watch with a resin band.
• Note that charging efficiency drops
when any part of the solar cell is
blocked by clothing, etc.
• Normally, you should try to keep the
watch outside of your sleeve as much
as possible. Charging is significantly
reduced if the face is only partially
covered.
Solar cell
After a full charge, timekeeping remains enabled for up to about six months.
• The following table shows the amount of time the watch needs to be exposed to light
each day in order to generate enough power for normal daily operations.

In this case:
• Time calibration auto receive is turned on whenever the transmitter mode is qvtA ,
DCF or MSF. Auto receive is off whenever the transmitter mode setting is OFF.
• See “To select the transmitter mode” below.
• Since the watch checks signals from both transmitters when qvtA is selected as the
transmitter mode, the signal receive operation can take as long as 12 minutes.
To select the transmitter mode
|| |||
||
1. In the Timekeeping Mode, hold down A until the city
code setting starts to flash, which indicates the setting
screen.
| | | || | |
2. Press C to display the transmitter mode setting screen.
3. Use D to scroll through available transmitter modes
until the one you want to select is displayed.
Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when you
last exited the mode appears first.
Radio-controlled Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time being set.
• Even when the watch is within the reception range of the transmitter, signal
reception is impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
• The time calibration signal is bounced off the ionosphere. Because of this, such
factors as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.
• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make.
• The watch is designed to automatically update the date and day of the week for the
period January 1, 2000 to December 31, 2099. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2100.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.
• Normally, the signal reception date shown by the Last Signal screen is the date data
included in the received time calibration signal. When only time data is received,
however, the Last Signal screen shows date as kept in the Timekeeping Mode at the
time of signal reception.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time within ±15 seconds a month at normal temperature.
• If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your transmitter, current city code, and
DST (summer time) settings. The following are the initial factory defaults for these
settings.

• To find out the module number of your watch, look at its
back cover. The Module number (2858, 2859, 2860, or
2861) will be engraved inside the box on the back cover.
Transmitters
This watch is designed to receive the time calibration signal transmitted from Rugby,
England and the signal from Mainflingen, Germany. You can select either one of the
transmitters, or you can configure the watch to automatically select the transmitter that
has the strongest signal.
• The following explains how the watch determines which transmitter it should check
first while the watch is configured for auto transmitter search.

Any case other than the above.
1. Checks the last successfully received
signal first.
2. If the last successfully received signal
cannot be received, checks the other
signal.

• If you leave the watch in the Time Recorder Mode or Alarm Mode for two or three
minutes without performing any operation, it automatically changes to the
Timekeeping Mode.
• If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically exits the setting screen.

4. Press A twice to exit the setting screen.
Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
• The day of the week is automatically displayed in accordance with the date (year,
month, and day) settings.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced or when battery power drops to
Level 4.
• The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Greenwich Mean Time (GMT) differential for each
city, based on your Home City time setting.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.
* The letters “UTC” stands for “Universal Time Coordinated”, which is the world-wide scientific
standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that
keep time accurately to within microseconds. Leap seconds are added or subtracted as
necessary to keep UTC in sync with the Earth’s rotation. The reference point for UTC is
Greenwich, England.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.
• With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and the A (AM) indicator appears for times in the range
of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
Power Saving Function
When turned on, the Power Saving function automatically puts the watch into a sleep
state whenever it is left for a certain period in an area where it is dark. The table below

Backlight Precautions
• The electro-luminescent panel that provides illumination loses power after very long
use.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• The backlight automatically turns off whenever an alarm sounds.
• Frequent use of the backlight shortens the battery operating time.
Auto light switch precautions
• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of
your arm can cause frequent activation of the auto light switch and illumination of the
display. To avoid running down the battery, turn off the auto light switch whenever
engaging in activities that might cause frequent illumination of the display.
• Note that wearing the watch under your sleeve while the auto light switch is turned
on can cause frequent illumination of the display and can run down the battery.
More than 15
degrees too high
• The backlight may not light if the face of the watch is
more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.
• The backlight turns off after about one second, even if
you keep the watch pointed towards your face.
• Static electricity or magnetic force can interfere with
proper operation of the auto light switch. If the backlight
does not light, try moving the watch back to the starting
position (parallel with the ground) and then tilt it back
toward you again. If this does not work, drop your arm
all the way down so it hangs at your side, and then bring
it back up again.
• Under certain conditions, the backlight may not light until about one second after you
turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.
• You may notice a very faint clicking sound coming from the watch when it is shaken
back and forth. This sound is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.
